one - Metallica 

I can't remember anything

Can't tell if this is true or dream
Deep down inside I feel the scream
This terrible silence stops in me

Now that the war is through with me

I'm waking up, I cannot see
That there is not much left of me
Nothing is real but pain now

heres half of the lyrics 

one is an anti - war song. This song is about a world war & about soldiers who's arms and legs got blown off by a landmine , also about the ones who were blind and couldnt move .
